Subject [jira] Updated: (HADOOP-4070) [Hive] Provide a mechanism for registering UDFs from the query language
Date Wed, 17 Sep 2008 14:31:47 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Tom White updated HADOOP-4070:

    Attachment: hadoop-4070-v2.patch

Here's an updated patch that addresses some of the comments.

* I've reverted the change to ExecDriver. (Set hive.aux.jars.path as a session variable to
pick up jars.)
* AdminWork is now FunctionWork. Other descriptors can be added to this class as needed.
* The syntax is now 
CREATE TEMPORARY FUNCTION my_udf AS 'com.example.MyUdf';
* I've added a client unit test which uses a test UDF packaged in a jar.

> UDFs (user defined functions) in Hive are currently actually built-in functions. This
issue is to develop a packaging and registration mechanism so users can add their own functions
at runtime.
